Soracom Air for Cellular plan-US-max now supports MO (Mobile Originated) SMS, giving IoT devices that use plan-US-max for connectivity the ability to send SMS messages.

In addition to the existing support for receiving MT (Mobile Terminated) SMS, this update now allows for bidirectional communication between devices and servers using SMS.

Please note that plan-US-max MO SMS support is limited to sending messages to the Unified Endpoint SMS address 901001. Data sent to Unified Endpoint can be stored in Soracom Harvest Data or forwarded to a different destination using another service such as Soracom Beam. Sending messages to other addresses is not supported.

For more information, please refer to the Sending Data with SMS & USSD documentation.

If you have any questions or concerns, please feel free to contact the Soracom support team.
